    E5TQ Series ChangeDisk Rotating Disk Electrode, PTFE

    Part Number
    AFE5TQ050

    The E5TQ ChangeDisk rotating disk electrode (RDE) tip is related to the E5 series RDE tips, but instead of a fixed, permanently mounted disk electrode, users can install and change the disk as desired. This electrode features an internal hardware assembly that can be installed and removed as desired from the ChangeDisk tip, using the E5TQ/E6 Series ChangeDisk Toolkit. The internal hardware assembly makes use of a consumable part to hold the disk securely in position without leaks, called the E5TQ/E6 ChangeDisk U-Cup. U-Cups work very well, but must be changed frequently (every 4 – 5 ChangeDisk operations is recommended) to ensure proper seal and performance. This tip accepts 5 mm OD disk inserts, from 4 mm thick to 1.5 mm thick. This ChangeDisk RDE tip is compatible with current MSR family electrode rotators when using the RDE shaft for 15 mm tips or the Precision RDE/RRDE Shaft shaft, and with and WaveVortex family electrode rotators, which have a compatible shaft that is permanently attached.

    Consumable U-Cups!
    The PTFE U-Cup is a consumable product for the ChangeDisk RDE and RRDE tips. To ensure proper operation and longevity of the tip, Pine Research recommends replacing the U-Cup every 3-4 times you perform a ChangeDisk operation. Permanent, irreversible damage to the tip will result if the U-Cup is not regularly changed. Consider purchase a backup supply when ordering a new ChangeDisk RDE or RRDE tip.
    Maximum Rotation Rate: 3000 RPM
    Never exceed maximum rotation rate when working with rotating electrodes.
    Shafts sold separately.
    Given the wide range of electrodes we offer, where each series requires one of several rotating shafts, shafts must be purchased separately for the MSR and MSR evo rotators. Consult the RDE, RRDE, and/or RCE specifications to learn which shaft is compatible.
    Maximum Rotation Rate
    All rotating electrodes, including RDE, RRDE, and RCE, have an assigned maximum rotation rate. The maximum rotation rate is specific to each electrode series. Do not exceed the maximum rotation rate when working with rotating electrodes.
    Thermal Stability Range: 10°C - 25°C
    Electrode damage may occur at temperatures beyond recommended range. This range is provided for electrodes with PTFE or PCTFE shrouds.
